This is a real cash flow business that you create for yourself. As Corn is a commodity, all you need is a commodity account from the commodities brokerage firm. The screen shots in the ebook will let you understand better. Download the ebook (found at the right side).

Hi Desmond, Thank you for your comments. To be successful in the Corn Business, we must first have proper risk management. We do not allow the price to drop below $5.00 in the example. In the rules stated in the eBook in page 15, when the price of Corn has moved against you and your Contract has doubled in value, the position shall be bought back and closed. The rules have to be strictly obeyed to ensure a successful Corn Business. Hope this helps. Do send me emails if you have further clarifications needed. Cheers!!
